End permian extinction cause
To paleontologists, the End-Permian Mass Extinction is the temporal boundary between the ancient paleozoic fauna and the modern fauna — a theoretical border between our world and a barely-recognizable predecessor. Finding Precision. As recent as the late 2000s, the research community was significantly divided over what caused the Permian ...The Permian-Triassic Mass Extinction (PTME) is the greatest biodiversity crisis in Earth history and while the marine crisis is increasingly well constrained, the timing and cause (s) of ...The Permian Triassic (P-T, P-Tr) extinction event, also known as the End Permian Extinction and very commonly known as the Great Dying, formed the boundary between the Permian and Triassic geologic periods. Not only within the periods but between the Paleozoic and Mesozoic eras, around approximately 251.9 million years ago.

“The end-Permian mass extinction may be less well known than the end-Cretaceous, but it was by far the biggest mass extinction of all time. Perhaps as few as 10 percent of species survived the end of the Permian, whereas 50 percent survived the end of the Cretaceous. Fifty percent extinction was associated with devastating environmental upheaval.Jul 1, 2003 · The biggest mass extinction of the past 600 million years (My), the end-Permian event (251 My ago), witnessed the loss of as much as 95% of all species on Earth.
